FUEL-VALVE.

Application filed December 3. 1917.

13e it knoivn that I, Ifnaxk (i. rinomati, a subject of the Iimperor ofAustria-lflungary, and resident of Chicago, in the county ot Cook and.State of Illinois. have invented certain new and useful Improvements inFuel-Valves. of which the following is a specification )I v inventionrelates to internal combustion engines and particularly to a novel fuelvalve for use in connection therewith.

My invention is particularly applicable to engines of the Hvid type;that is, those in which ignition is effected by the heat of compressionand in which the liquid fuel charge inhaled on the intake stroke In allof the engines of the type in which liquid fuel is fed directly to theengine, the fuel valve must of necessity be of small dimensions; thisfor the reason that the amount offuel necessary to be supplied for eachpovver stroke is minute. and a small particle of foreign matter whichmay lodge on the valve seat vvill prevent the closing of the valve andthe escape of the high pressure of the cylinder into the fuel conduit,thusblovving out its contents. Thesedifli culties follow the use of anyvalve which lifts from its seat. An object in this invention is toprovide a valve which never leaves its seat but rotates thereon, thuseliminating the difficulties heretofore referred to. This is readilyaccomplished in an engine of this type wherein the fuel valve is of suchrelativelv small size. the rotary movement of the valve tio-'fully openand close the liquid intake port extending over only a feiv degrees.

l' The invention ivill be more readily understood by reference to theaccompanying drawings, ivherein,

Figure l is a vertical section through one end of an engine constructedin accordance with my invention;

I"ig. 2 is a plan vieiv thereof;

Fig. 3 is a bottom plan vieu' of the fuel valve,

tion cup l0", at the lovver end thereof, this being of the type commonlyemployed in engines of this type. 'Ihe intake valve I2 is operated by arocker 123, fulcrumed on the top of the cylinder and in this instanceprovided ivith an arm li, ivhich serves to actuate the fuel valve. Inorder to accomplish this. a link l5, is connected to the arm and is inturn connected to an arm IG, secured to the valve stem 1T. A compressionspring IS, surrounds the valve stem and tends to exert an upvvard pullthereon. The valve 1s in the form of a notched disk 19. the tivo notchesheilig formed on diametricl sides of the disk and When in one positionthe notches register With the outlets or ports of oil and air passages:20, 2l. IVhen the valve is rotated a feiv degrees the oil and air portsare closed. Oil is supplied through a pipe :22, which may be controlledbv a valve u In the construction shown in I: ig. the valve is in theform of a circular disk QI, having diametricaily disposed apertures 25,2G. which are spaced in accordance with the ports from the oil and airpassages.

rI`he advantage of the valve in the construction shown in Figs. I to 3inclusive is that the sharp edge formed by the notched portion of thevalve serves to scrape the valve seat at each actuation `and thusprevent the lodgment of any particles of foreign matter. Furthermore, itivill be noted that this valve is never actuated against any pressureother than the pressure of the spring which serves to seat the valve,the rotary actuation occurring only at the beginning and end of theintake stroke.

It ivill be apparent that the extent ot' opening of the valve or thelength of time during which it is opened or both may be controlled by agovernor in any suitable manner. rIliis is contemplated by me. It willfurthermore be apparent that if desired a needle valve may be installedin the fuel passage. i

The valve may be modified in other par- 'ticulars than that shown; thatis, it may be 2 reime?
